Patented Feb. 21, 1950 PAD FOR, IRONER ROLLS Harry 0. Mamaux, Pittsburgh, Pa., assignor to Pittsburgh Waterproof Company, Pittsburgh, Pa., a corporation of Pennsylvania Application November 5, 1947, Serial N o. 784,199

This invention relates to padding for ironer rolls such as those used in iiatwork ironing. In devices of this character, a iibrous pad is commonly placed around the ironer roll, the pad having a cloth covering to support the work as it is moved past the ironer shoe or steam chest. The major portion of the ironing pressures occurs at the middle zone of the roll, with the result that the padding becomes compacted at the circumferential mid zone of the roll, and the pad therefore becomes set to a concave condition at said zone, and furthermore, the ends of the cylindricallywrapped pad iiare somewhat. Further ironing operations are therefore diflicult because of the non-uniformity in diameter of the pad.

Attempts have been made to overcome this distortion of the padding to a concave contour at its mid portion, as by initially forming the pad of greater thickness at its mid zone than at its edges, to thereby provide more material at said zone, and thus produce a crowned effect, the thickened zone of material becoming compacted in use until the pad is of more or less uniform thickness or diameter. However, such a solution is not entirely satisfactory, because initially the pad does not have the desired uniform cylindrical contour.

My invention has for its object the provision of means whereby the pad not only will have the proper cylindrical contour and uniform diameter when it is first put into use, but will retain such contour during a longer period of use than is the case with pads of other forms.

In the accompanying drawing, Figure 1 is a sectional view through a pad made according to my present invention; Fig. 2 is a fragmentary view showing the manner in which my padvis mounted upon an ironer, the section through the pad being taken on the line II-II of Fig. 1, and Fig. 3 is a schematic view indicating the manner in which a pad of conventional form becomes compacted or guttered after a short period of use.

In Fig. 3, the dotted lines 4 indicate the original thickness of a common form of pad throughout its entire width, whereas the full lines at 5 show the manner in which it will become compacted or guttered after a period of use.

As shown in Fig. 1, my pad comprises warp roves 6 which may conveniently be formed of cotton, held in unitary relation to one another by weft threads 1, these padding elements being connected to reinforcing facing fabric 8 and 9, by stitching 9a, it being also intended that the relatively smooth fabric 8-9 can be incorporated with the padding elements 6--1 in any other suitable manner.

My invention resides in the fact that the roves 6 are assembled somewhat compactly with respect to one another near the mid zone of the 2 Claims. (Cl. ,6G- 190) padwhile toward the edges thereof, the roves are spaced farther apart. For example, at I0 the roves are spaced slightly apart while at II, each rove may be spaced apart a distance equal to the thickness of each rove.

The result is that that portion of the pad which overlies the circumferential mid zone of an ironer cylinder I2 will have greater resistance to ironing pressure than those portions of the pad at I0 and l I, for example, near the ends of the ironer roll. Since the ironing pressure will not be so great or so frequently applied at points toward the ends of the ironer roll, the resistance to ironing pressures should not be as great at the end zones, and therefore, the pad as a whole will maintain its cylindrical contour during use better than pads of conventional construction. Also, the pad when initially applied to the cylinder I2 has the true cylindrical contour necessary for good ironing operations, as distinguished from pads which initially are of crowned contour.

I claim as my invention: r

1. Anironing roll pad adapted to be wrapped around an ironer roll and having roves therein which, at the longitudinal mid zone of the pad, are in more closely-spaced relation to one another than near the edges of the pad, weft threads holding the roves in assembled relation, and a relatively smooth facing fabric unitarily connected with the weft threads and the roves.

2. An ironing roll pad adapted to be wrapped around an ironer roll and having roves therein which, at the longitudinal mid zone of the pad, are in more closely-spaced relation to one another than near the edges of the pad, weft threads holding the roves in assembled relation, and a relatively smooth fabric unitarily connected with the weft threads and the roves throughout each face of the pad.
